上虞绿色防控试点茶园虫害发生情况调研

An investigation on the occurrence of pests at the green prevention and control tea garden in Shangyu County

在浙江上虞地区天香茶园设置吸入式太阳能杀虫灯和黄色诱虫板开展茶园绿色防控工作,并以当地无特殊管理措施的金家茶园作为自然条件下茶树虫害发生模式参照,调查2018年6月-2020年8月期间两处茶园的茶小绿叶蝉、螨类、茶尺蠖、蓟马、蚜虫的发生情况。调查结果显示,天香茶园和金家茶园茶小绿叶蝉、螨类、蓟马和蚜虫的虫口高峰期均出现在每年的8-10月,而螨类的小高峰还出现在4-5月,其中茶橙瘿螨和蓟马数量在绿色防控技术干预下明显减少。调查期间未见茶尺蠖爆发。可见,绿色防控能有效降低相关害虫的虫口数,但不改变其发生规律。

The green prevention and control technology was used out in the Tianxiang tea plantation in Shangyu District(Shaoxing,Zhejiang Province),through installing inhalation solar insecticidal lamps and yellow sticky pest trap.The occurrence of pests during June 2018 and August 2020,including tea green leafhopper,tea geometrid,tea mites,tea aphids and tea thrips,was investigated,with the local Jinjia plantation without intervention as the natural occurrence pattern control.The results showed that the population of tea green leafhopper,tea mites,tea aphids and tea thrips at both tea plantations showed a single peak from August to October annually,while tea mites had its second population peak from April to May.Besides,the populations of tea mites and tea thrips were reduced under tea garden green prevention and control.No burst of tea geometrid was observed during the investigation period.Thus,green prevention and control technology is considered to be effective for controlling the population of specific insects without affecting the occurrence pattern.
